I should mention, my problem with my tailgate, was that the window tends to go down too far, ???? and in my case the cable got stuffed up into the window gears and got chewed up that way. So I bought a Cardone motor five years ago when I restored my Blazer, and I had an extra power cable which is why I found the LMC and the GM replacement the same color and connections, kinda odd I thought ? But rockauto site says the Cardone #82200 is brand new, and the Cardone #4220 is a rebuild. I also see Rockauto sells CMK 4145423811S tailgate felts for the 2 guide rails in the tailgate, You might want to see how yours are, I did and replaced mine, after 30 years, they are pretty much shot. Tightens up the window operation. I bought a can of WD-40 Specialist Water-Resistant Silicone spray and soak down your side felts and it helps the window work a lot better.
